In a binary solution, the component present in smaller proportion is called solute while the one in excess is known as solvent. The solution containing 1 mole of the solute in 1L of solution is known as one molar solution while the solution in which 1 mole of solute is dissolved in 1 kg of the solvent is called one molal solution. The ratio of the no. of moles of a particular component to the total no. of moles in the solution is known as its mole fraciton 1.57 g of oxalic acid (COOH)_(2)xH_(2)O are dissolved in water and the volume is made upto 250 mL. On titrating 6.68 mL of this solution requires 25 mL of N/15 NaOH solution for complete neutralisation. The value of x is :
